    Abstract: A facsimile device in which plural sets of recording medium can be provided. While images are recorded on one set of recording medium, the first set is changed over to another set of recording medium by a change-over signal transmitted from a control section of the facsimile device, after finishing recording the images being received on the first set. Thereafter, the images can be recorded on the other set. An image memory is provided for storing image data transmitted during the time period for changing over the recording medium. The image data received are accumulated in the image memory during the change-over and when finished, the accumulated image data are read out in order from the image memory and recorded on the other set of recording medium.

    Abstract: An image data processing apparatus capable of high-speed encoding even for intermittently supplied image data is provided with a memory storing image data, an encoder for encoding the image data and/or a decoder for decoding such encoded information and a transfer unit for DMA transfer of the image data from the memory to the encoder. A supply may be provided for supplying the encoder with the reference signals in synchronization with the DMA transfer of the image data by the transfer unit. The encoding and/or decoding are performed intermittently, e.g., in response to supply of the reference signals.

    Abstract: A dot matrix copying device includes optical rectification apparatus comprising storage means for storing image information in dot matrix form and means for transferring the stored information to a dot matrix print head. The image information is derived by simultaneously scanning an original document and an optical grating positioned adjacent thereto and directing the scanned scene toward an array of photosensing elements, one of which is positioned to view the optical grating. The optical data so derived is stored in the storage means under timing control of the photosensing element which views the optical grating.

    Abstract: A device and method for providing real time compensation for packet loss in the transmission of facsimile data over packet networks to avoid the generation of page loss data and the termination of facsimile transmission. Facsimile devices have a low tolerance for interruptions in transmission. Packet networks commonly have a transmission interruption rate above the tolerance of facsimile equipment. In order to compensate for transmission interruption, the present invention teaches the buffering of facsimile data by scan line at the receiving end, the evaluation of buffered scan lines for packet loss and the discarding of scan lines having packet loss to conceal the packet loss from the receiving facsimile equipment to avoid detection of page errors by the receiving facsimile equipment which could cause loss of facsimile transmission. Discarding damaged scan lines instead of repair or replacement saves computational time and storage capacity, allowing for real-time compensation to provide for optimal transmission.

    Abstract: An image input section (1) reads an image on a document, and simultaneously output image data (S1) of a plurality of pixels. An input image converting section (4) generates second image data (S2) continuing in a sub-scanning direction based on image data (S1). An image processing section (3) provides a predetermined image processing to the image data (S2) to generate third image data (S3). An image output section (5) forms a duplicating image of an image on the document by simultaneously using a plurality of laser devices (L1 to L4) corresponding to each pixel based on the third image data (S3). Image data whose plurality of pixels is simultaneously input is arrayed and adjusted to be applied to a multi-beam output. As a result, an image processing for obtaining a high quality of the duplicating image can be performed at high speed.
